Jest fails with TypeError: react_native_1.Dimensions.addEventListener is not a function

[NathHorrigan]

While writing a test for createText I came across an issue regarding missing fields on the Dimensions object.
This seems to be an ongoing issue for the repo, however I am unable to mock the code the module manually:

jest.mock('react-native/Libraries/Utilities/Dimensions', () => {
  return {
    get: () => ({
      width: 375,
      height: 667,
    }),
    addEventListener: jest.fn(),
  };
});

Have you any suggestions?

This was fixed by using https://github.com/callstack/react-native-testing-library

I think adding some instructions to README regarding testing, in general, would be quite beneficial :)

Apart from the issue, the library looks great, Thanks for your hard work!

@NathHorrigan I'm getting this error still. Could you provide a little more detail on how you fixed this?

We've migrated to the useWindowDimensions from react-native. We mock this hook in the library as such: https://github.com/Shopify/restyle/blob/master/src/test/createRestyleComponent.test.tsx#L53-L55

Please, reopen with reproduction steps if this is still an issue.

@fortmarek is there any way to use useWindowDimensions outside component like in util functions we can use Dimensions.get in util function but after React Native 0.73.8 upgrade jest unit tests are failing for below error so could you or any one please help regarding this issue
TypeError: Dimensions.get is not a function
